Hi Amit, Global Send Key is a higher-level interface that sends keystrokes to the active application. Thus they are an example of operations that needs an active application. Send Keys will work for most applications and should be tried before Send Key Events. Send Key Events works for all applications and is the text sending method recommended for Citrix applications. It is a lower-level interface that mimics keyboard keystrokes in operating system. Send Keys and Send Key Events are the part of the interface techniques that make up the Blue Prism Surface Automation interface.
Global keystrokes should be used when other methods of inputting text do not work, either because a thin client technology such as Citrix is being used, or because the element within an application either cannot be identified by application modeller or does not accept the use of a write stage. If one interface method of sending text to an application does not work a developer should move onto trying a different method until a technique that works is found.
